The U.S. Environmental Protection Agency (EPA) has completed its third periodic review of the cleanup of polychlorinated biphenyls (PCBs) in the Upper Hudson River. The review evaluates the progress of the long-term project aimed at restoring water quality and reducing PCB levels in fish and sediment.
Overview of the EPA’s Review Process
After gathering public input, the EPA analyzed project data collected between 2016 and 2021. This data includes water quality, fish contamination, and sediment analysis, along with additional fish sampling results from 2022.
The agency’s findings highlight a significant overall decrease in PCB levels in both water and fish. However, the EPA emphasizes the need for additional fish data to fully assess the long-term recovery trends.
Why Additional Fish Data Is Essential
The EPA requires at least eight years of fish data post-dredging to develop a science-based understanding of recovery rates. The eighth year of data collection concluded in 2024.
According to the EPA, this comprehensive dataset will help confirm whether recovery trends align with the project’s goals and expected timelines. The results from the 2024 fish sampling are anticipated to be available in 2025.
Next Steps: Report Addendum Timeline
To provide a complete assessment, the EPA will release an addendum to its review report once sufficient fish data is available. This addendum is expected to offer a more detailed evaluation of recovery progress.
- Expected Release: The addendum could be published as early as 2025.
- Final Deadline: No later than 2027.
Conclusion: Progress and Future Updates
The EPA’s review confirms positive trends in reducing PCB levels in the Upper Hudson River, but continued monitoring is crucial. The upcoming report addendum will provide a clearer picture of the recovery process and help guide future environmental efforts.
